DuctSox - Redefining Air Dispersion

DuctSox Corporation, headquartered in Dubuque, Iowa, is a manufacturer of custom engineered commercial and industrial fabric air dispersion products for open ceiling architecture, critical environments, and underfloor applications.

During the 1980’s the company known today as DuctSox began providing air dispersion solutions to the food processing industry. During this time food processing plants were looking for an air dispersion product that would provide more precise and efficient air control than they were achieving from their current metal systems. The solution was fabric air dispersion. DuctSox provided a custom engineered air dispersion system that met the exact needs of each space along with all the added benefits that come along with using a fabric system. These benefits include lower material and labor costs, no risk of condensation, lower maintenance, noise absorption and aesthetically pleasing

DuctSox’s commitment to quality, service, and innovation has led to the expansion of the traditional fabric offerings to include USDA approved fabrics, an adjustable flow device, custom color and patterned fabrics and new products such as fabric drop plenum diffusers, sound attenuators, and the patented SkeleCore internal framework systems.

These innovations make DuctSox the perfect air dispersion solution for any space and variety of environments.  Applications include food processing plants, laboratories, data centers, growing facilities, schools/universities, sports venues, airport hangers, warehouses/distribution centers, along with industrial manufacturing facilities and much more.

DuctSox has become a proven leader in the HVAC industry with their products accepted within key industry organizations such as ASHRAE, Underwriters Laboratories (U.S. & Canada), International Code Council, and many building authorities throughout the world.
